The problem with the current PlayBook OS is that no content (not counting Bridge) will be push to your device unless you have the actual app window open. And this is an actual native app developed by RIM. This problem also applies to the BlackBerry Podcasts app. This also means no push notifications from: Facebook, Twitter, weather system alerts, breaking news, etc.

On the other hand, on your "old school" BlackBerry phone everything will be push to your phone regardless if you have the app open or not.

They really need to improve the push/pull services on this new platform, as well as a solid notification system. For a company who supposedly prides themselves as "nobody does communication better than us" they certainly haven't proved that with the PlayBook OS and 2.0 doesn't fix any of these issues stated above.
